1660 shutting down

[Mud Mechanik]

I have had my 1660 for around a year or so, and have been pleased so far. It just recently developed a habit that i wish would stop, about every 3rd crank or so it starts but im:confused3:mediately shuts back down. The dash lights go out just like i turned the key off. It will crank right back up and does fine. Is anyone else experiencing this with a massey cut?

I haven't experienced it with mine, starts fine and keeps running but mine has no hours on it yet.

Curious that the dash lights turn off, I bought the shop manual with mine but don't have it here with me. Have you gone through the starter circuitry to check connections for security / moisture etc?

 

[Mud Mechanik]

I have checked all of them, it acts like the ignition switch itself is very sloppy and is shutting tractor back off.

 

[Mike476]

That's a possibility, while I've read other manufacturers' tractors experiencing difficulty with their ignition swiches it usually related to moisture ingress on open station tractors.

I took the heavy dealer cast dealership logo off the keys I was given with the tractor, ever since having to replace the ignition switch on my '76 Monte Carlo many moons ago I've used leather for key chains.

I would tend to not believe this is moisture related, it is in a cab and the tractor spends all of it's down time in a climate controlled shop.

Is there enough weight on the seat? Mine had a similar problem with light operator on board. I finally disabled the seat switch, because it started doing it when I was driving (I weigh 250 lbs) when backing up.

 

[Mud Mechanik]

I weigh 275, though I have never given any thought to the seat switch, I will look into it, Thanks.

Cannot be the seat switch, you don't have to be seated to start tractor.

 

[Mike476]

Never tried it on mine, I thought having the protection switch was "standard issue". Might not be required for cab tractors? :confused3:

Quick look at the 1660 manual under troublshooting the only thing I see that makes sense that it might be is the neutral switch.

I am leaning more toward ignition related only because its killing the dash lights and the neutral switch is tied in on the start side. The dash lights and fuel shutoff solenoid is tied to the run side.
I guess you have made sure its plugged in good.
I would also unplug it, remove it and look for a loose pin on the switch itself.


It would help me to better understand if you can answer these:

does it ever do it sitting still idling or does it always do it while you are working (moving).
does it kill the radio
does it kill the blower motor on the heat/ac
does it ever start to die and then misfire and begin running fine again
how long in between incidents every 5 minutes every hour is it getting worse as to when it does it.

Also I have seen people try and turn the key to far to the left when shutting it off and messing up the internals of the switch making it loose fitting and sloppy.
Are you the first owner of this tractor?

You dont have a wad of keys hanging on the key chain as Mike476 mentioned earlier.

Have you found mouse crap/ mouse nest anywhere in the cab - could be a chewed up wire.

Sorry for all the questions

Just an update, after testing the ignition switch, I found a loose spot that would lose contact when the key was wiggled. My dealer sent me a new switch, I replaced it and problem is gone.
